Abstract
Computational fluid dynamics（CFD）modeling and experiments have both advantages and disadvantages. Doing both can be complementary, and more effective understanding of the phenomenon can be expected. It is useful to utilize CFD as an efficient tool for the turbomachinery and can complement uncertain experimental results. However the CFD simulation takes a long time for a design in general. It is necessary to reduce the calculation time for many design conditions. In this
paper, it is attempted to obtain the more accurate characteristics of a wind turbine in yawed flow conditions for a short time, using a few grid points. It is discussed for the reliability of the experimental results and the CFD results.
